The lands were once home to thousands of bison. Now deer, antelope, elk, moose, beaver, and coyote roam.

The road, 101 miles long, takes about three hours to travel. It starts in Fort Collins and goes through Roosevelt National Forest, then follows the river through Poudre Canyon up to Cameron Pass and down to North Park.

Cache La Poudre is a French phrase from the trappers that means roughly “place to keep powder.”

The road passes through the Arapahoe National Wildlife Refuge, a popular spot for bird watching, and North Park, Colorado’s northernmost natural park, a high-elevation grassland.
